This Apple Cinnamon Blondies recipe turns a handful of pantry basics into a fudgy, buttery bar packed with real apple chunks and warm cinnamon flavor. Every bite has that soft, chewy blondie texture with little pockets of tender apple throughout, and a whisper of cinnamon glaze on top. They come together in one bowl, bake in about half an hour, and disappear from the counter almost as fast.

Ingredients
1/2cupunsalted butter113g, melted
1cuplight brown sugar200g, packed
1large egg
2teaspoonspure vanilla extract10ml
1 1/2cupsall purpose flour190g
1teaspoonVietnamese cinnamonplus more for the glaze, can substitute with regular ground cinnamon
1/2teaspoonbaking powder
1/4teaspoonbaking soda
1/4teaspoonsalt
1 1/2cupsGranny Smith applesabout 2 medium apples, peeled and diced small (pea-sized)
1/2cupchopped pecans60g, optional
1/2cuppowdered sugar60g, for the glaze
1 to 2tablespoonsmilk15-30ml, for the glaze
Instructions
Preheat oven to 350°F. Line an 8x8 baking pan with parchment paper leaving an overhang on two sides, and lightly spray with nonstick cooking spray.
Peel and dice the Granny Smith apples into small, uniform pieces about the size of a pea. Set aside.
In a large mixing bowl, whisk together the melted butter and brown sugar until smooth and glossy. Add the egg and vanilla extract, and whisk until fully combined.
Sprinkle the flour, cinnamon, baking powder, baking soda, and salt over the wet mixture. Fold with a rubber spatula just until no dry streaks of flour remain. Do not overmix.
Add the diced apples and chopped pecans (if using) to the batter, and gently fold until evenly distributed. Avoid crushing the apple pieces.
Transfer the thick batter to the prepared pan and spread evenly into the corners using a spatula. Wet the spatula slightly to prevent sticking.
Bake for 30 to 35 minutes, until the top is golden brown and a toothpick inserted in the center comes out with a few moist crumbs. Start checking at 28 minutes.
Cool completely in the pan on a wire rack for at least 1 hour before lifting out using the parchment overhang. For cleanest slices, chill for 30 minutes before cutting.
Whisk the powdered sugar, milk, and a pinch of cinnamon until smooth and pourable. Drizzle over the cooled blondies and let set for about 10 minutes before serving.
Notes
Use firm, tart apples like Granny Smith so they hold their shape instead of turning to mush during baking.
Dice the apples small and uniform for even cooking throughout the batter.
Let the melted butter cool slightly before adding the egg to prevent it from scrambling.
Do not overmix once the flour is added, or the texture will turn cakey instead of fudgy.
Pull the pan out slightly early if you prefer an extra gooey center.
Let the bars cool fully before slicing for clean, sharp edges.
Swap pecans for walnuts or hazelnuts, or fold in white chocolate or cinnamon chips.
Store in an airtight container at room temperature for up to 4 days, refrigerate for up to 1 week, or freeze individually wrapped squares for up to 3 months.
Warm briefly in the microwave for 10-15 seconds for that fresh-baked texture.
Skip the glaze entirely and dust with powdered sugar for a simpler finish.
